SaniFlow STU-01, 316L sanitary filter housing by Exova

Description

The SaniFlow STU-01 is an AISI 316L stainless steel sanitary filter housing for one cartridge, designed for liquid filtration in the pharmaceutical and biotech industries. It holds 2 1/2″ sanitary-code cartridges with a 226 or 222 double O-ring, with fin or flat end, from 10″ to 40″.

The interior is polished to Ra 0.4 µm and the exterior to Ra 0.8 µm. The T-type design, with a drain at the lowest point, reduces dead volume and fully removes cleaning solutions and product residues.

It operates up to 10 bar and 140 °C, and is sterilized in place (SIP) or in an autoclave. The vent and drain, with hose connect/disconnect valves, make the cartridge integrity test easier. It is ordered with or without legs and with silicone, Viton or PTFE-coated Viton gaskets.

Interior polished to Ra 0.4 µm

AISI 316L stainless steel body with the interior polished to Ra 0.4 µm and the exterior to Ra 0.8 µm.

Reduced dead volume

Frequently asked questions

Which cartridges does the STU-01 accept?

2 1/2″ sanitary-code cartridges with a 226 or 222 double O-ring and a fin or flat end (configurations B, C, D and E), from 10″ to 40″. The ordering code also includes 5″.

Can it be sterilized in place?

Yes. It can be sterilized in place (SIP) and is autoclavable, with a maximum operating temperature of 140 °C and a maximum pressure of 10 bar.

What gaskets does it use?

Silicone gaskets; on request, Viton or PTFE-coated Viton. They are selected in the code (A, V or R).

Does it allow the cartridge integrity test?

Yes. The vent and drain with hose connect/disconnect valves make the integrity test and the draining of the entire vessel easier.

Can it be integrated into a filtration skid?

Yes. We custom-design sanitary plug-and-play skids with housings, valves and instrumentation on a fixed or mobile frame: prefiltration and final filtration, triple stage, parallel or duty/standby lines, bypass and recirculation, with drains at low points, vents at high points and ΔP measurement.
